tööravitust
Tööravitust, also known as work hardening or strain hardening, is a metallurgical phenomenon where the yield strength of a metal increases after plastic deformation. This process occurs due to the movement of dislocations within the metal's crystal structure. As the metal is deformed, dislocations become entangled and pinned, making it more difficult for further deformation to occur. This increased resistance to plastic deformation results in a higher yield strength.
Tööravitust is commonly observed in metals subjected to cold working processes, such as rolling, drawing, or
However, tööravitust also has its limitations. Excessive work hardening can lead to a decrease in ductility,
In summary, tööravitust is a valuable metallurgical process that enhances the strength and hardness of metals
